Reterrii-,rr to thevdrawinos onrtionleriv i nl 7 i 'l and@i e portion of e "railroad track Vis Shown"comprising therails and cross i eingindioated ihjv the its top and is journaled therein, being held in place by suitable nuts screwed onto the threaded ends thereof. An arm 16 is carried on the shaft and forms a signal, the same being shown as having the word Stop thereon adjacent one end. rllhe arm 16 ei;- tends at both sides et shaft 15 and is adapted to swing trom a horizontal operative position shown in `lull lines in Fig. 3 to substantially vertical inoperative position shown in dotted lines in said ligure. it. pinion 17 is secured to shaft 15 and engaged by a gear segment 1S herebeneath carried on a shaft 1Sa similar to shaft 15, which segment has an arm' connected by a flexible member shown as a chain 19, and a weight 2O guided i'ior movement between the members 141.a and within a U-shap'ed casing 14k" secured thereto. The weight acting through members 18 and 1T normally tends to hold the arms 15 in its inoperative position. rlfhe weight 20 has spaced passages 20FL therethrough in which are disposed headed bolts 21 held in place by cotter pins 22 extending therethrough and disposed in holes 2Ob in the weight 2 Coiled compression springs 23 surround the bolts 21 between the bottom oli weight 2O and the plate 2st through which said bolts also pass and below which their heads are disposed, said plate 2Libeing ot the same cross-sectional size and shape as the weight 2O and being guided therewith in the casing 14". A lever 25 is provided carried on a pivot extending through members 1d'Lt and 1&1 and having its inner end disposed beneath the plate 2d. Lever 25 pivotally connected at its outer end to a link 26 which, in turn, is pivotally connected at its upper end to another lever 2? also pivoted on a bolt extending throuf-rh men'ibers 1-/1n and equipped with bolts at its threaded ends holding` it in place. The lever 2T at its inner end is pivotally connected to a curved link 28 which is, in turn, pivotal'iy connected atits lower end to one end ot a crank Q9 carried on the shaft 30 journaled in the members 11i and Mb and projecting at one side oit said members. The shaft 80 is also journaled in a small bracket 31 (Fig. 8) at one end oll the trame members 1st and has a crank arm 32 adjacent its outer end. rlhe crank arm 32 is pivotally connected to a link 33 which is, in turn, pivotally connected at its other end to a pivot n'iember 3d- (Fig. 9) shown as a rivet with its ends countersunk in the spaced sides ol a lever Z55, which lever is pivoted at its low er end .in the center of a bracket 36 bolted to the underside ot ay pair of cross ties 11 by headed and nntted bolts 3? which also extend through the horizontal and outwardly extending flanges 38a ol' a pair ot spaced Ushaped brackets 38 bolted to the top of said cross ties 11. The lever has disposed between its spaced arms and adjacent the tween the top thereoi3 a stop member 89 having a flat horizontal top. A lever 40 is pivoted bearms ot lever above stop 39 and has a -lat-rally projecting arm 10FL engaging stop 39, said .arm being held in engagement witl said stop by a coiled tension i cnw` said arms and also sewer end to the link 33. The

its lo lever 10 has is vertical arm disposed adjacent one ot the rails 10, as shown in Fig. 1. A link l2 is also pivotally connected to rivet 3st and entends parallel with the rails 10 at the outer side thereof through a suit-- able guide bracket 43 carrying spaced guide rollers /l-Lt, which bracket is secured to the cross ties 11 by suitable headed and nutted bolts. '.llhe other end ot link 4:2 is threaded into the cylindrical and tapped end of a yoke L15 having a block 46 secured between the spaced ends thereof by a headed rivet, which block is pierced by the cylindrical 'threaded end ot a link L19 having a stop nut adapted lo engage the outer end of block t6 and having a nut 18 adjacent its inner a coiled compression spring being disposed between nut i8 and block lib and surrounding link 49. The end oli' link '4t2 is provided with a jam'b nut engaging the end voke 45. The other end o1 link is pi'forally connected to the lower end oit' a lever 150 comprising spaced sides, which lever is inte .nediately pivoted on a headed and nntted bolt 51 extending through the top central portion of a pair of U-shaped lnackets having outwardly extending lateral flanges secured to the cross ties 11 by 4able headed and nutted bolts. A block secured between the sides of lever 50 no Uf) and has a projecting hook-shaped arm over which is secured the lower end of a coiled te. sion spring 5ft, the upper end of which is engaged over a laterally extending arm 55 of a lever 55 similar to the lever LlO. T he arm is held against the top flat surface oit a block 5G anchored between the sides olf lever 5G by the spring 54:. The structure above described, it will be seen, is duplicated at both sides of the track extending te the lett at the bottom ot Fig. 1, and extending to the right ot trame 14; at the top of 1 The bottom ot each 'frame 14 is provided with a pair of holes through which extends vertically extending pins 58 connected to a cross bar 58a. The cross bar 58a normally rests upon a lever 59 pivoted between a pair ot brackets G0 bolted to the bottom of trame le and depending therefrom. The brackets 60 are curved and carry therebetween adjacent their lower ends a roller 61. fr longitudinally movable rod 62 rests upon the roller 61 and has a vertical arm 63 upstanding therefrom bifurcated at its upper end and provided with a cam roller 64 adapted to enga-ge the curved underside of lever 59. Therod `62`has`an intermediate cylindrical portion which passes through a'conduit 65 `eXtend1ngbeneath the highway 12 "intoa' pit 66 at the other side oi the highway,

67 has a' slotted yupper end engagingV a pin or screw 69 projecting from the outer end o1"- a crank arm 7 O secured to one end oi a shalt 71 journaled in a pair of spaced bearings 7 :2 bolted to the top otplate 66a. rEhe shaft 71 carries at its other' end an varin 73, the outer endet which is'connected to a link 74 similarin all respects to link 33. l'llhe other end oit link '74 is `connected to the intermediate portion of a' lever 75, said lever and parts carried therebylsimilar in all respects to the lever 35 and the parts carried thereby, al-

"ready ldescribed, and pivoted to a bracket 76 sirnil'arjin Vall respects to the bracket 36 lalready"described and lmovable between a -pai'r of brackets 77 similar in all respects to the bracket 38 alreadydescribed. The lever 75 also has connected thereto a link 7 8 simii larinall"respects to link 42, which is also movable through one or more guide brackets 43 and between rollers 44 therein. The link 78 has a yoke 79 connected thereto similar inl all respects to the yoke 45, which yoke is connected, in the 'manner already described with a link 8O pivotally connected to the lower end of a lever 81'siniilar in all respects to the lever 5,0 and, like said lever 50, pivoted between a pairoi brackets 81a similar in all respects to the brackets 52, said lever 81 having a lever 82 at the top thereof similar in all respects to lever 55, already described. structure from the link 74 tothe lever S2 is similar in all respects to the structure extentling rom'link 38 to the lever 55 and need not be again specilically described. lt will be seen from inspection oit Fig'. 1, that the parts designated from 74 to 82 are duplicated ato'pposite sides `of the track, said structure beingr shown at the right hand of Fig. 1 and at the bottom thereof and also at the lett hand olf said iigure at the top thereof.

.An arin83 (Fig. 3) is pivoted on a headed and nutted bolt or studV 83h in one oit the plates 14a and has an auxiliary arrn 83 ex- .tending` therefrom. The arm 83a' is adapted tofengage 'onel edge `of the signal arm 16 at the .iecess 16EL therein when said arm begins its movement tohorir/iont-all position. The arin'SS is apertured tofreceive a pin'84 upstanding, fromfand securedto 'one side ol link 7 28 `at`it`s`iipperend, aeoiledsprifng l85 sur- `is bsiegeenlinieas 'alla' i The width to be engaged by t-lieupper end oi a pin 86 extending upward from the upper side of weight 20, a spring 87 also surrounding` pin 86 and adapted to engage the under side of arm 83. Pin 85 and spring 87 have their upper portions broken away in 4, but are fully shown in Fig. 3.
